e1000e: move force SMBUS from enable ulp function to avoid PHY loss issue
[ Upstream commit 861e8086029e003305750b4126ecd6617465f5c7 ]
Forcing SMBUS inside the ULP enabling flow leads to sporadic PHY loss on
some systems. It is suspected to be caused by initiating PHY transactions
before the interface settles.
Separating this configuration from the ULP enabling flow and moving it to
the shutdown function allows enough time for the interface to settle and
avoids adding a delay.
Fixes: 6607c99e7034 ("e1000e: i219 - fix to enable both ULP and EEE in Sx state")
